The present invention relates to a window-type natural ventilation device, in particular to adopt a natural convection ventilation structure using the temperature difference between the inside and outside and the air pressure according to the blowing, as well as to improve the assembly performance and cost reduction with a simple structure. The present invention relates to a window-type natural ventilation device whose structure has been improved.

In general, the role of the window is to act as a mining role to receive light and to ventilate the indoor and outdoor air by opening and closing the window.

Contaminated indoor air causes many diseases in the human body, and in particular, various dusts and microorganisms in the contaminated air cause respiratory diseases and allergies, and various pollutants (formaldehyde, volatile organic substances) emitted from indoor building materials. , Asbestos powder) causes diseases such as headache, cough and itching.

Therefore, it is preferable to ventilate the interior and exterior to frequently ventilate the air so that various contaminants do not accumulate in the interior.

By the way, the conventional window has a problem that a strong wind flows in the case of opening the window to ventilate or the rain water or dust from the outside is introduced into the room.

In addition, in the case of existing windows, the air containing soot flows directly into the room in the process of simply entering the outside air, thereby not only losing the function of the ventilation itself but, in more severe cases, worse than the outside air. There was a risk of inflow.

In order to solve this problem, Utility Model Registration No. 20-216482 forms a ventilating hole before and after the window frame, and inside the ventilating connecting the front plate having a small pore set in front and the rear plate having a hole in the rear with a spacer.
